Abstract:
Due to the short wavelengths in millimeter waves and the specific characteristics of wave propagation in this frequency band, the methods used for modeling channel response in lower frequency bands are not applicable without appropriate modifications. Considering the fact that many obstacles in the channel have sizes comparable to the wavelength (eg branches and tree leaves, brick spacing and roughness height of many surfaces), statistical-empirical methods can be an efficient way of modeling propagation in the presence of such components.
Here an attempt has been made to obtain an appropriate model for the propagation channel using propagation models proposed in the literature. Surface roughness, precipitation and propagation through vegetation have been included in this model.
The impact of various propagation mechanisms such as diffraction and rough surface scatter, along with the properties of the channel response throughout the environment has been studied. Ultimately, a simple semi-empirical model has been proposed based on the street canyon model and has shown acceptable correspondence with ray tracing results
